The Election Calculator
is based on the available software for counting votes
and simultaneously calculates the results of an election based on a long and growing
list of election methods and their variations.
It can be used to calculate results for a small election (< 30 votes) or to experiment
with what-if scenarios in voting theory.

Advocacy

Election method issues are often left unconsidered.
I think most of the advocacy right now needs to be around raising awareness and getting people to the point of "yeah, that would be a good idea".
Of course, the laws are being changed in some places and jumping to that step is great if it works.
Until then:

promote the advantages of being able to safely vote your conscience without strategy or compromise

point out elections that go to a small plurality (less than 40%) and wonder aloud if there might have been a majority which preferred a different outcome.
